A variant of a common herpes virus may play a role in the development of multiple sclerosis (MS), Swedish researchers say.
They analyzed the blood of about 8,700 MS patients and a control group of more than 7,200 people without MS. They were looking for antibodies against proteins of two variants (A and B) of human herpesvirus 6 (HHV-6), which has been linked with MS.
The latest version of the so-called artificial pancreas system helped people with type 1 diabetes gain even better control of their blood sugar levels than current technology does, a new study reports.
The device combines an insulin pump, a continuous glucose monitor and a computer algorithm. The system measures blood sugar levels and delivers insulin automatically when levels rise. ...
Children diagnosed with type 1 diabetes at an early age have slowed growth in brain areas linked to mild cognitive deficits, new research suggests.
The study compared MRIs of the brain in kids with type 1 diabetes to age-matched children without the condition. Researchers also saw that areas of slower brain growth were associated with higher average blood sugar levels.
The idea behind immunotherapy for peanut allergy is appealing in its simplicity: Ask a patient to eat tiny amounts of peanut every day, and over time their immune system will become desensitized to it.
Unfortunately, this cure might be doing more harm than the allergy itself, a new evidence review suggests.
People who undergo immunotherapy for their peanut allergies wind up with...
Almost one in five multiple sclerosis patients may be misdiagnosed with the autoimmune disease, according to a new study.
Of 241 previously diagnosed multiple sclerosis (MS) patients referred to two major Los Angeles medical centers for treatment, nearly 18% did not actually have the autoimmune disease, the researchers found.
Patients with kidney failure who are on dialysis or have received a transplant have a sharply higher risk of dying from cancer, Australian researchers report.
In fact, compared with people who don't have kidney failure, they have more than double the odds of cancer death. The odds are particularly high among patients aged 20 to 34, for whom the risk is 11 times higher, the researcher...
HPV vaccination rates for younger American adolescents are alarmingly low, researchers say.
"While we have seen gains in HPV vaccination coverage, we are still falling behind at the younger ages," said study lead author Robert Bednarczyk. He'sassistant professor of global health and epidemiology at Emory University in Atlanta.
Human papillomavirus (HPV) is a sexually transmi...
People who take prescription opioid painkillers are at increased risk for pneumonia, especially those with HIV, a new study suggests.
The findings support concerns that prescription opioids can weaken the immune system. Doctors who prescribe opioids need to reduce patients' risk of pneumonia through vaccination and by encouraging them to stop smoking, the researchers said.
More than 10 percent of U.S. adults have a food allergy -- and nearly double that believe they do, a new study estimates.
Researchers found that 19 percent of those surveyed thought they had a food allergy. But when the investigators dug into people's symptoms, they found that only 10.8 percent reported "convincing" signs of a true allergy.
Deaths and complications among pregnant women with lupus have declined in the United States over the past two decades, a new study finds.
Lupus, also called systemic lupus erythematosus (SLE), is a chronic autoimmune disease that causes inflammation in many parts of the body, including the kidneys, skin and joints, as well as the tissue lining the lungs, heart and brain.
The gluten-free diet craze is both reassuring and upsetting to people with celiac disease who are allergic to the nutrient, a small study suggests.
People with celiac disease say they're happy to have more food choices at stores and restaurants. But some with celiac sense a growing stigma as other people voluntarily go gluten-free. And many patients fear people see them as "high-main...
It's not always easy -- even for doctors -- to tell if someone has type 1 or type 2 diabetes when they're diagnosed as an adult.
And a new study finds mistakes are common.
That's what happened to British Prime Minister Theresa May when she was diagnosed with type 2 diabetes in 2012. She was in her 50s at the time. Despite having all of the symptoms common to type 1 diabetes...
Though psoriasis is not contagious, many Americans shun people with the skin condition, new research indicates.
The study included a cross-section of about 400 Americans who viewed images of people with visible psoriasis. Large numbers wrongly thought psoriasis was contagious or only affects the skin, and about one-third said they wouldn't want to invite people with the condition into...
A baby's immune system kicks into high gear immediately after birth, a new study finds.
Changes in a newborn's immune system have been difficult to assess because doing so has relied on samples taken from the umbilical cord immediately after birth. In this study, researchers used a new immune cell analysis technique to follow 100 premature and full-term babies for their first few week...
Organ transplant recipients are at increased risk for skin cancer and need to protect themselves, a dermatologist warns.
"Individuals who receive organ transplants need to take immunosuppressive medications for the rest of their lives, and this makes it more difficult for their bodies to fight disease, including skin cancer," said Dr. Christina Lee Chung. She is former director of th...
Trauma or intense stress may up your odds of developing an autoimmune disease, a new study suggests.
Comparing more than 106,000 people who had stress disorders with more than 1 million people without them, researchers found that stress was tied to a 36 percent greater risk of developing 41 autoimmune diseases, including rheumatoid arthritis, psoriasis, Crohn's disease and celiac dise...
Sometimes life's sudden shocks or illnesses can turn hair gray -- Barbara Bush, the former first lady who passed away in April, reportedly had her brown hair turn gray as a young mother, following a daughter's tragic death.
But how does premature graying happen? Scientists say new animal research may help clear up the mystery.
The mouse studies suggest there's a link between...
Doctors have discovered a combination of treatments that can return color to skin that has been lightened by vitiligo -- the skin disease that turned Michael Jackson's skin white.
The new therapy includes the oral medication Xeljanz (tofacitinib) -- a drug already approved for use in rheumatoid arthritis patients that dampens the body's immune response -- and ultraviolet-B light ther...
The worst flu season in years is only getting worse, with 49 states now seeing widespread misery, U.S. health officials report.
"Flu is everywhere in the U.S. right now," Dr. Daniel Jernigan, director of the U.S. Centers for Disease Control and Prevention's influenza division, said during a media briefing Friday. On a map of the United States tracking flu activity, "this is the first...
Babies born with the immune-system ravaging "bubble boy" disease have had to spend their too-often-short lives in germ-free isolation, lest something as simple as a common cold virus fell them with a fatal infection.
But after decades of research, doctors now believe they have created a cure for severe combined immunodeficiency (SCID).
